Pericardial tumors are rare cardiovascular disorders, with an incidence of 0.001% to 0.007% and account for 6.7% to 12.8% of primary cardiac tumors.

2
A 60-year-old woman with a pericardial paraganglioma underwent transcatheter embolization of a circumflex artery fistula, leading to significant tumor regression.
-
3
Multimodal imaging, including CT and MRI, was essential for diagnosing the pericardial tumor and planning its non-surgical management.
-
4
Post-embolization, the patient's urinary catecholamine levels normalized, and she reported substantial resolution of symptoms at the one-year follow-up.

5
This case demonstrates the potential of targeted embolization as a non-surgical treatment option for inoperable pericardial paragangliomas.
